Abstract

In this study, polyester resin composites were reinforced with varying ratios of Aluminum Oxide (Al₂O₃) and Silicon Carbide (SiC) powders, and their mechanical properties were systematically investigated. The composite samples were subjected to compressive strength tests and Specific Energy Absorption (SEA) evaluations. The Response Surface Methodology (RSM) was employed to perform a statistical analysis of the experimental results, allowing for the determination of significant factors and their interactions. The compressive strength of the composites was found to be significantly influenced by the content of Al₂O₃ with the highest compressive strength observed at a composition of 95% resin, 1.66% SiC, and 3.33% Al₂O₃, yielding a maximum stress of 8895.48 MPa. Similarly, the SEA results demonstrated that the addition of 3.33% Al₂O₃ and 6.66% SiC led to a remarkable improvement in energy absorption capabilities, achieving an SEA value of 73.20 J/kg. The statistical analysis confirmed the significance of both the individual and interaction effects of the filler materials, with p-values indicating high significance (p < 0.05). The developed models exhibited high accuracy with R² values of 0.9245 for compressive strength and 0.9492 for SEA, suggesting the reliability of the experimental data. These findings underline the potential of using ceramic powders like Al₂O₃ and SiC in enhancing the mechanical performance of polyester resin composites, making them suitable for high-performance applications.

基于响应面法的碳化硅与氧化铝增强聚酯树脂复合材料的实验与统计分析

本研究采用不同比例的氧化铝（Al2O3）和碳化硅（SiC）粉末对聚酯树脂复合材料进行增强，并对其力学性能进行了系统研究。对复合材料试样进行了抗压强度试验和比能吸收（SEA）评价。采用响应面法（RSM）对实验结果进行统计分析，确定显著因素及其相互作用。Al2O3含量对复合材料的抗压强度有显著影响，在树脂含量为95%、SiC含量为1.66%、Al2O3含量为3.33%时，复合材料的抗压强度最高，最大应力为8895.48 MPa。同样，SEA结果表明，3.33% Al2O3和6.66% SiC的加入显著提高了材料的能量吸收能力，SEA值达到73.20 J/kg。统计分析证实了填料材料的个体效应和交互效应的显著性，p值表示高显著性（p < 0.05）。所建立的模型具有较高的精度，抗压强度R2值为0.9245，SEA R2值为0.9492，表明了实验数据的可靠性。这些发现强调了Al2O3和SiC等陶瓷粉末在提高聚酯树脂复合材料机械性能方面的潜力，使其适用于高性能应用。图形抽象

期刊介绍： The journal Silicon is intended to serve all those involved in studying the role of silicon as an enabling element in materials science. There are no restrictions on disciplinary boundaries provided the focus is on silicon-based materials or adds significantly to the understanding of such materials. Accordingly, such contributions are welcome in the areas of inorganic and organic chemistry, physics, biology, engineering, nanoscience, environmental science, electronics and optoelectronics, and modeling and theory. Relevant silicon-based materials include, but are not limited to, semiconductors, polymers, composites, ceramics, glasses, coatings, resins, composites, small molecules, and thin films.
